TRAMWAY FOR ELEVATED RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 366,627, dated July 12,1887.

Application filed March 7, N87. Serial No. 230,009. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. HAMIL- TON, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inTramways for Elevated Railways; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to tramways for elevated railways.

The object is to provide a structure whereby an elevated railway may becarried through a street already occupied by a horse, cable, or otherroad without in any wise interfering with these or with the right of wayof their cars.

The invention consists in a post for a tramway, divided to form an archor the like.

The invention furthermore consists in a support for a tramway, composedof an arch constructed to straddle a track or roadway, and supporting apost or column.

The invention finally consists in various novel details ofconstruction,whereby the purposes of the invention are accomplished.

In the accompanying drawings, forming part of this specification, and inwhich like letters of reference indicate corresponding parts, Figure 1is a view in vertical crossseetion of a tramway embodying features ofthe invention. Fig. 2 is a view in side elevation of the same.

A represents a post or column, one of a series upon which the tramway islaid,and which is principally composed of the side pieces, a, formingthe upper portion, A, and lower bifurcated portion, A

In the upper portion, A, the side pieces or uprights, a, are broughtclosely together to form a post or column, and are braced or fastenedtogether by side plates, 1), thus forming an open and light yet firmsupport. The sides of the capital of this column are carried outward andform struts, upon which the tramway rests. I

At the bottom of his column A the side pieces are bent outward andslightly inclined, as shown at a, to 1forn. an arch, and are then bentinward to form slightly-inclined uprights a for the sides of the archand support of the column, their lower ends being embedded and braced inany preferred manner to form a firm and solid support.

The upper ends of the inclined uprights are braced together by means ofa beam, 1), (shown in dotted lines,) and inclosed by plates 1), fastenedat each end to the uprights a which plates, at their centers, areprovided with braces or trusses D which form a support between theplates b and the arched portion of the side pieces, a to meet the strainbrought to bear thereon by the weight of the tramway and cars. By thismeans of support for an elevated tramway Very little space is occupiedupon the ground, the sides of the col'. nmns being of light yet strongconstruction, and straddling the track in the manner shown will permitof its occupying a position directly above a street-railway or cableroad without in the least interfering with its cars or right of way.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. A post for a tramway,divided to form an arch or the like,substantially as described.

2. A support for a tramway,composed of an arch constructed to straddle atrack or roadway and supporting a single line of posts orcolumns,substantially as shown and described.

3. A post for elevated tramways, formed of uprights suitabl y securedtogether, forming a post above, and bent outward at their lower ends toform an arch below, substantially as shown.

4. In a post for elevated tramways, the combination ofthe uprights orside pieces separated at their lower ends to form an arch, the bracesfor securing them together, the beam between the separated ends, platesfor connecting the uprights and securing the beam in place, and bracesbetween said plate and arch portions, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

BENJAMIN F. HAMILTON.
